Today I got an error when selecting the “VMware EVC” option in the Cluster Settings at my vCenter 4.0 host with multiple HP Blades with same CPU. Error message:
Method not found: ‘Vmomi.HostSystemArray EVCState.get_BadSoftwareHostsBlockingEVC()’
Solution:
This issue occurs when a system installed with vSphere 4.1 and you use vSphere 4.0 Client on that system to access vCenter Server 4.0.
To workaround this issue, install a vSphere 4.0 Client on a system on which you have not installed vSphere4.1 Client earlier and then update the EVC cluster using the vSphere 4.0 Client.

Today I got some problems with backing up one of my VM’s using VMware Data Recovery. I was looking what was going wrong after a few failures.. And yes.. hanging snapshots
Trying to remove the snapshots was a little bit different. When I went into the “Snapshot Manager” there were no active snapshots and I couldn’t delete the files. But while browsing the Datastore I saw many active snapshots.
Current situation:
– You can “Revert to Current Snapshot” via menu..

Today tried to import the ESX Deployment Appliance (EDA) in vCenter 4, but after File > Deploy OVF template > selecting destination host I received this error message:
Device ‘VirtualCdrom’ uses a controller that is not supported. This is a general limitation to the virtual machine’s virtual hardware version on the selected host
To modify the VMware Hardware Version from default version 7 to 4 you can use the VMware vCenter Converter Standalone 4.0.1 Now I was able to import the EDA Appliance in my vCenter.
